Description
The XA9536XL is a 3.3V CPLD targeted for high-perfor-
mance, low-voltage automotive applications. It is comprised
of two 54V18 Function Blocks, providing 800 usable gates
with propagation delays of 15.5 ns. See Figure 2 for archi-
tecture overview.
Power Estimation
Power dissipation in CPLDs can vary substantially depend-
ing on the system frequency, design application and output
loading. Each macrocell in an XA9500XL automotive device
must be configured for low-power mode (default mode for
XA9500XL devices). In addition, unused product-terms and
macrocells are automatically deactivated by the software to
further conserve power.
For a general estimate of I_CC, the following equation may be
used:
I_CC(mA) = MC(0.052*PT + 0.272) + 0.04 * MC_TOG*MC* f
where:
MC = # macrocells
PT = average number of product terms per macrocell
f = maximum clock frequency
MC_TOG = average % of flip-flops toggling per clock
(~12%)
This calculation was derived from laboratory measurements
of an XA9500XL part filled with 16-bit counters and allowing
a single output (the LSB) to be enabled. The actual I_CC
value varies with the design application and should be veri-
fied during normal system operation. Figure 1 shows the
above estimation in a graphical form. For a more detailed
discussion of power consumption in this device, see Xilinx
application note XAPP114, “Understanding XC9500XL
CPLD Power.”
